This work contains the study results of climatophilous vegetation series from Serra da Estrela, the highest
mountain on the Portuguese mainland. Located in central-northern Portugal in the Estrelensean Sector (Carpetan-Leonese
Subprovince), the Serra da Estrela has several bioclimatic stages, mainly resulting from slope and altitude ranges:
mesomediterranean, submediterranean mesotemperate, supramediterranean, submediterranean supratemperate, and submediterranean
orotemperate. In each of these belts are observed changes in plant communities that determine variations
in terms of the vegetation series. The methodology was based on Dynamic-Catenal Phytosociology. The results show the
presence of five climatophilous series; their structural characteristics and dynamics are described in this paper: 1.

pyrenaicae S.; 4. Arbuto–Querco pyrenaicae cytisetoso grandiflori S.; e 5. Viburno tini–Querco roboris S
